The Catalinbread Dirty Little Secret (DLS) MKIII Red is a limited-edition "Marshall-in-a-box" overdrive pedal that delivers the blistering, amp-smashing gain of a cranked 1970s British stack. It features a modified circuit with clearer low-mids, a hi-fi EQ, and blistering gain across both voicing modes.

Key Features & Controls

• Two Distinct Voicings: An internal slider switch lets you toggle between Super Lead (SL) for high-gain bite and harmonic detail, and Super Bass (SB) for a slightly thicker, in-between overdrive tone.
• 3-Band EQ: Dedicated Treble, Middle, and Bass knobs that exactly reproduce the tone-stack circuits of vintage Marshall amps.
• Pre-Amp & Master: Controls that allow you to balance the gain and volume to get cranked-amp tones even at bedroom practice volumes.
• Internal Presence Trimpot: Accessible by removing the bottom plate, this lets you fine-tune the high-treble and presence frequencies to perfectly match your guitar and amp.
